320640 divided by 50 
We're looking to find how many times 50 goes into 320640.

Moving on to step 1:
The number 50 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 50

Let's proceed to step 2:
32 divided by 50 is 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 50

Moving on to step 3:
320 divided by 50 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 20 after subtracting 300 from 320.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 50

On to step 4:
50 can be fit into 206 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 200 from 206 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 50

Moving on to step 5:
50 goes into 64 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 641.0
The remainder is 14 after subtracting 50 from 64.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 50

Moving on to step 6:
140 divided by 50 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 6412.0
If we take 100 away from 140, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
If we divide 400 by 50, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 6412.8
Subtracting 400 from 400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6412.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6412.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 6412.8 and a remainder of 0.0.
